No, if there is oil inside with the spark plug, it means the seals in the valve cover are leaking. These seal kits can be purchased with the valve cover and can be easily replaced once the valve cover is removed. Be sure to clean all the excess oil from around the spark plug well. I use "brake cleaner" in a can, and compressed air to clean them out in my shop. Be sure to cover the area with a shop towell to avoid making a mess.
No there should not be any oil where you plug your spark plugs into
R45TS
The rotor inside the distributor should be pointing at the #1 spark plug.
The easiest way to find out is to remove the wire from the spark plug and hold it about 1/4 inch from ground (the engine block is good) while someone cranks the engine in short bursts. If you are getting spark you should see a blue spark jump fromt the wire to the engine block. You might want to check all spark plug wires while you're at it. If you want to check the spark plug while you're at it, remove the spark plug and attach it to the end of the wire before checking for spark. If you get spark through wire but not through the spark plug, the spark plug is bad.
Remove the spark plug from the engine. Attach the wire to the spark plug. Let the spark plug come in contact with the engine block. Make sure the ignition is turned on. If you have a safety bar you will have to pull it into operating mode. Pull the starter rope you should see a spark.
No.
Remove the spark plug wire from the spark plug. Use some heavy gloves or a set of insulated pliers to hold the spark plug wire about 1/4-inch from the engine block (ground) and crank the engine - you should see a spark jump from the wire to the engine ground. For a better check, use another spark plug and put it on the spark plug wire and use it as a "jumper" from the wire to the engine ground.
On a carburetors motor pull the coil wire from the distributor cap (the plug wire in the center of the distributor). This is usually found between the air cleaner and the firewall. Remove the desired spark plug from the engine block, plug it into the coil wire and touch the spark plug body (the metal portion) to the engine block while cranking the engine. You will see spark if the plug is good.
that should have the HEI distributor so the plugs should be set at .045
You should never need to replace the wires leading to the spark plugs. The 2003 Miata has a coil pack at each spark plug (inside the spark plug hole). The wires leading to the coils are low voltage and should never break down.
It should be under the spark plug wires connector block.
It should be the same as the small block.18436572.
